Description

Method, device and system for the sharing of position data in mobile terminals

The subject matter relates to a device, a system and a method for controlling a mobile terminal, which is connected via a short-distance radio to at least one other mobile terminal, and which is connected to a server for sending and receiving information. The subject matter further relates to an apparatus, a system and a method for controlling the server.

In the mobile market are mobile devices with many

different equipment and features used, these mobile devices can be classified, for example, in the classes low-end, mid-end and high-end. In general, only the most in the high-end range

settled mobile terminals via precise means for

Localization of the device, e.g. through a built-in GPS receiver. All other mobile devices can only rely on a very inaccurate cell location by the network operator. Especially with large cells falls one

Position determination based on the cell location extremely inaccurate.

These mobile devices without their own exact

Localization are, however, much more common in the market represented as the high-priced equipped with a GPS receiver high-end devices. From WO 2009/076942 a method is known in which encounters between two mobile devices are detected by a mobile device and encounter data is transmitted to a server. However, the recorded encounters are free from positional data. Thus, while it is possible to detect an encounter by having a physical proximity between two users, no position data is exchanged between an active device, the server, and a passive device. Also, passive devices are not assigned positional data.

Based on the identified disadvantages of the application, the object of the invention was to provide a method, a mobile device, a server, as well as a Computerprograinm available, which in a simple and flexible way localization of no separate means for

Localization comprehensive mobile devices allows. The object derived above and outlined in the prior art is solved according to an object by a method for controlling a mobile terminal. In this case, at least one identifying identification of at least one further mobile terminal is received by the mobile terminal via a short-distance radio, and position information and the information comprising at least one identifying identification are sent to a server by the mobile terminal. Furthermore, the object is achieved by a mobile terminal, wherein the mobile terminal has a first communication module, which is set up via a Short-range radio network, and comprises a processor, which is adapted to carry out the method described above. Furthermore, the object is achieved by a computer program for controlling a mobile terminal, which controls the mobile terminal such that at least one identifying identification of at least one further mobile terminal is received via a short-distance radio, and

Positional data and the at least one characteristic

Identification comprehensive information is sent to a server.

The short-range radio can, for example, a

Short-range radio network, such as Bluetooth®, Wireless LAN, Near Field Communications (NFC) or similar

Short-range radio network, and the mobile

Terminals are set up to send and / or receive data via this short-range radio. For example, the method may include switching on a short-distance radio in the mobile terminal, so that subsequently a self-organized short-distance radio network between the mobile terminal and the at least one other mobile terminal is established.

The mobile terminal receives identifications identifying short-range radio from at least one other mobile terminal. This identifying identification comprises information that uniquely identifies the respective mobile terminal so that the respective mobile terminal can be identified on the basis of the identifying identification. This identifying identification can thus For example, represent a one-to-one identifier of a respective mobile terminal.

The identifying received from the mobile terminal

Identifications can thus be used, for example, as a list of the others in a short-range radio

Short-range radio network contained mobile terminals are considered. The mobile terminal is further adapted to the

collected identifier identifying the other mobile devices together with position data to a server. This can also be the characteristic

Identification of the mobile terminal to be transmitted. If the server has this information, e.g. due to the connection between the mobile terminal and the server, the identifying information of the mobile terminal need not be transmitted to the server. These mobile terminals may be set up, via another radio network, e.g. a cellular network such as e.g. GSM, UMTS, HSDPA, LTE or other mobile network can communicate. The other radio network has a higher range than short-range radio. Thus, the mobile terminal of this additional wireless network for

Use transmission of the collected identifying identifications together with the position data to the server. The mobile terminal can, for example, another

Communication module for communication over the further

Radio network may include, but may also be the first

Communication module for communication over the further

Radio network be set up. The position data may be any position data representing the location of at least one of the mobile terminals of the short-range radio

Describe short-range radio network. This can e.g. the

Be position of the mobile terminal itself, or the position of at least one of the at least one other mobile

Terminal, or a combination thereof. Therefore, suppose that at least one of the mobile

Terminal comprises a device for determining position. This device for position determination can be, for example, a satellite-based position determination unit, such as a GPS receiver for determining GPS-based position data, a Galileo receiver for

Determination of Galileo-based position data, a GLONASS receiver for the determination of GLONASS-based position data, but it can also be another receiver for

Determine determination of position data. These

Location data can be, for example, location coordinates

represent, e.g. in Cartesian representation or in

Polar coordinate form, or position data in another suitable form, such. Latitude and longitude straight. The position data can also be height information

include.

For example, by sending the identifying information and the location data, the server may assign position information to each of the mobile terminals.

According to an advantageous embodiment is a

Method proposed for controlling the server, which receiving information from a mobile terminal, which information comprises at least one

identifying identification of at least one other mobile terminal and position data, wherein the mobile terminal and the at least one further mobile

Terminal are connected via a short-range radio, which comprises determining at least one group of adjacent mobile terminals based on the received

Includes information, and which comprises determining and assigning position information to each of the at least one determined group.

According to an advantageous embodiment, a server is proposed with a processor, wherein the processor is adapted to the method described above for

To control a server.

According to an advantageous embodiment is a

Computer program for controlling a server proposed, wherein the computer program performs the method described above for controlling a server.

According to an advantageous embodiment, a system with at least one of the above and / or below

suggested mobile terminals and the server proposed.

For example, if only position data for a single mobile terminal is on the short-range radio

trained short-range radio network, so the server can, for example, a group determine such that all mobile devices of the short-range radio network are included in this group, the determined and this Group assigned position information can correspond to the position data of a mobile terminal. Since all mobile terminals are connected via the short-range radio network, the mobile terminals are arranged spatially close, so that the position information assigned to the group is more accurate than, for example, the location information of a mobile radio cell in which the group is located.

For example, supposing that several of the mobile terminals can provide location data via a short-distance network formed by the short-range radio, the server can determine, for example based on these location data, which of the mobile terminals are spatially close together in groups, and these are spatially close located mobile devices m

divide different groups, and these groups

assign different position information based on the plurality of received position data. Thus, an even higher spatial accuracy posted by the groups

assigned position information can be achieved.

The server may be further configured to be one of a plurality of short-range radio

Short-range radio networks receive information, each identifying identifications of the mobile

Terminals m the respective short-distance radio networks and position data include. Thus, the server can do this

each different short-range radio networks in each case in at least one group of spatially adjacent mobile terminals and assign each group a position information. According to an advantageous embodiment, it is proposed that the position data include the position data from one of the at least one further mobile terminal, which are received via the short-distance radio.

Thus, position data of at least one

another mobile device to determine the

Position information of a group to be taken into account. According to an advantageous embodiment is

proposed that the mobile terminal queries its own position data, and the transmitted position data includes this own position data. Thus, position data of the mobile terminal, which sends the information to the server, can also be taken into account for determining the position information of a group. Accordingly, the mobile terminal comprises means for determining position.

According to an advantageous embodiment is

suggested that the mobile terminal over the

Short-range radio additional position-related information about at least one of the other mobile terminals with respect to that formed by the short-range radio

Short-range radio network receives, and that the information sent this additional position-related

Information includes. This additional position-related information can, for example, represent information from the mutual location of the mobile terminals via the short-distance radio. These additional positional information will be

for example, by the mutual communication of the mobile terminals in the short-range radio

trained short-range radio network and transmitted to the mobile terminal, which is connectable to the server. The information sent by this mobile terminal to the server may also include additional location-related information about this mobile terminal with respect to the trained short-range radio network,

For example, these position-related information may be suitable for the structure or the topology of the

Map short-stretch network server side, so that this information can be used to determine the at least one group and / or can also be used to determine the position information for at least one group.

According to an advantageous embodiment is

suggested that the additional position-related

Information comprises at least one of the following information: information as to whether the respective mobile terminal is a master or slave device; Information with which

other mobile terminals, the respective mobile terminal is connected directly via the short-range radio network; and information about a measure of the receive field strength of the

Short-range radio link with which the respective mobile terminal with another mobile terminal on the

Short-range radio network is connected.

The information as to whether a mobile terminal is a master or a slave device, for example, from the server to do so can be used to determine subnetworks of a short-distance network formed by the short-distance radio, which can be used, for example, for grouping the mobile terminals. For example, a subnetwork can be made up of a master device and the direct

connected slave devices are formed.

The information with which other mobile terminals a respective mobile terminal is connected, can

For example, on the server side to replicate the structure of the formed by the short-distance radio

Short-distance network can be used.

The information about a measure of the reception field strength of a short-distance radio connection with which the respective mobile terminal with another mobile terminal on the

Short distance radio is connected, for example, can be used as an indicator of a distance between the respective and the other mobile terminal. If the measure of reception field strength is relatively weak, e.g. the

Grouping of the mobile terminals are carried out so that a mobile terminal is assigned to a first group and the other mobile terminal is assigned to a second group, so that a separation of the two mobile terminals

with regard to the divided groups. If there is a high degree of reception field strength between the respective and the further mobile terminal, these two mobile terminals can be assigned to the same group, for example.

According to an advantageous embodiment is

proposed that one trained by the short-distance radio Short distance radio network comprises at least one subnetwork and the additional positional information includes information as to which subnetwork of the

Short distance radio network is associated with the respective mobile terminal.

For example, the short distance radio network may be a self-organizing ad hoc network consisting of multiple piconets interconnected. These piconets thus represent

Subnetworks. The mobile terminals in themselves

Organized ad hoc network may be set up to collect information about the affiliation of each mobile device with respect to the piconet networks. This information may be considered additional positional

Information is sent to the server and there used for grouping and / or determination of the position information for at least one group. According to an advantageous exemplary embodiment

suggested that the server-side determine the

at least one group pre-grouping the mobile

Includes terminals by subnetworks. The information about the affiliation of the individual mobile terminals with respect to the subnetworks can be used, for example, for a pre-grouping of the mobile terminals, since it can be assumed that the mobile terminals m are spatially close to a subnetwork. However, based on further information, the server may change this pre-grouping again.

For example, this may be the case if a mobile Terminal of a subnetwork a connection with higher field strength to a mobile terminal of another

Subnetwork has while the connection of the mobile terminal to the original subnetwork has a lower field strength.

According to an advantageous embodiment is

suggested that the server-side determine the

at least one group determining locations of the mobile terminals to each other in a by the

Short-range radio trained short-range radio network includes.

These locations can, for example, by the additional position-related information and / or on

Basis of the received position data are determined. Depending on the particular locations, the grouping of the mobile terminals can subsequently take place in groups of spatially adjacent mobile terminals.

For example, information from the further wireless network can also be used for determining the location. For example, if the other radio network is a cellular network, and mobile terminals of the short distance radio network are in

different cells of the other wireless network, so this assignment of the mobile devices to different cells of the other wireless network, for example for a

Pre-grouping of mobile devices are used.

According to an advantageous embodiment is

suggested that determining a position information to a determined group on the basis of position data of at least one mobile terminal of this group.

If, for example, position data are available for exactly one of the mobile terminals in a group, these can

Position data can be used as position information for this group. If, for example, position data for several mobile terminals of a group are present, then

For example, an average value of the present position data can be used to determine the group-related position information.

According to an advantageous embodiment is

proposed that the determination of a position information to a determined group on the basis of position data from mobile terminals of at least one adjacent group is carried out.

The neighboring groups can be determined, for example, via the additional position-related information explained above.

For example, if there are none for the identified group

Position data before, the position information of this group can be estimated, for example, based on position data from mobile terminals of at least one adjacent group. But even if position data is available for the determined group, the position data of mobile terminals of neighboring groups can be used to assist in the determination of the position information. This can be done, for example, if only position data from a mobile terminal within the detected group, and this mobile terminal of the network structure of the short-range radio

trained short-range radio network is not in the middle of the group, which, for example, by a small

Field strength could be displayed to acting as a server mobile terminal in this group.

According to an advantageous embodiment is

proposed that the position data from at least two mobile terminals from at least two adjacent groups are used to determine the position information.

Thus, the position information for the determined group can be determined, for example, from an averaging of the different position data of the at least two mobile terminals of the at least two adjacent groups.

If, for example, position data from mobile terminals are present from at least three adjacent groups, the position information can be obtained from a cross-bearing based on these position data. Furthermore, the

Position information of the adjacent groups, which can indeed be based on the respective position data, are used to estimate the position information of the determined groups.

According to an advantageous embodiment is

suggested that the server select a group of at least one group and to that selected group

sends group-specific data. After the server has the at least one group for the

Short-range radio network has formed and each of these at least one group has assigned a position information, the server can, for example, targeted groups

select and predeterminable to these groups

Assign behavioral instructions as group-related data.

For this purpose, the server, for example, this

Send behavioral instructions in the form of group-related data to a mobile terminal of the respective group, so that this mobile device further sends these behavioral instructions to the other mobile terminal of this group, the

However, for example, the server can also contact each mobile terminal of a group individually.

After the group-specific data has been received from the respective mobile terminals, these mobile terminals can be used, for example, in the

execute behavioral instructions contained in group-specific data.

According to an advantageous embodiment is

proposed that the server receives the information from the mobile terminal via another wireless network.

This further radio network can e.g. a cellular network such as e.g. GSM, UMTS, HSDPA, LTE or another mobile network. The other wireless network has a higher range than short-range radio.

According to an advantageous embodiment is

suggested that determining the at least one group on neighboring mobile terminals based on

Position information of the other wireless network is done.

For example, if the other wireless network is a cellular network, then there are mobile ones

Terminal devices of the short-range radio network in different cells of the other radio network, this assignment of the mobile terminal to different cells of the other radio network can be used for example for grouping the mobile terminal.

According to an advantageous exemplary embodiment

proposed that the determination of the position information based on position information of the other

Radio network is done.

For example, the position information of a cell of a mobile network for the determination of

Position information for a group to be used with.

According to an advantageous exemplary embodiment

proposed that the server sends the group-specific data to a mobile terminal of the selected group and instructs this mobile terminal to send the group-specific data to the other mobile terminals of this selected group via the short-range radio network. According to an advantageous embodiment, a computer program for controlling a server is further proposed, so that the server is a group of at least one group selects and sends group-specific data to this selected group.

According to an advantageous embodiment, a method for controlling a mobile terminal is further provided

proposed by receiving group-specific data and instruction data from a server, wherein the

Instruction data includes a list with at least one other mobile terminal, and by sending the

group-specific data to the at least one other mobile terminal via a short-range radio network.

According to an advantageous embodiment, a program for controlling a mobile terminal is further proposed, by receiving group-specific data and from

Instruction data from a server, wherein the instruction data comprises a list with at least one further mobile terminal, and by sending the group-specific data to the at least one further mobile terminal via a

Short-range radio network.

On the mobile terminal, for example, a client may be installed that is configured to receive group-specific data from the server and the aforementioned ones

To receive instruction data. Based on the group-specific data received, the mobile terminal may send the group-specific data to the other mobile terminals designated in the instruction data via the

Send short-range radio network.

Thus, the server, for example, per selected group only a radio contact over the other wireless network to a set up a selected mobile device while the

Group-specific data can be subsequently distributed from this mobile terminal via the short-range radio network to the other mobile devices of this group.

However, the server can also directly send the group-specific data to several or all mobile terminals of a selected group, for example via the previously

explained another wireless network.

For example, you can target traffic jams

Instructions may be sent to mobile terminals from selected groups, for example, to form escape lanes or to maintain ideal speeds

energy efficient or lead to a faster resolution of a traffic jam. At major events can

for example, public flows are better managed. In stadiums and at concerts, for example, through deliberately timed standing and arm movements, a variety of waves can be generated or by coordinated display animations lighting effects can be generated.

Furthermore, a system is presented which comprises at least one of the mobile terminals described above and one of the servers described above.

various mobile terminals 11-21 according to a first exemplary embodiment of the present invention. This first exemplary embodiment is described below together with the method illustrated in FIG. 2a according to a further exemplary embodiment for controlling a mobile terminal and with the method illustrated in FIG. 2b according to another exemplary embodiment for controlling a server. These mobile terminals 11-21 are adapted to communicate over a short distance radio, e.g. Bluetooth®, wireless LAN or the like to record radio contact with another mobile terminal 11-21 and to send and / or receive data via this short distance radio. This

Short-range radio can thus form a short-range radio network 30.

Furthermore, these mobile terminals 11-21 are

established via another radio network 50, e.g. GSM, UMTS, HSDPA, LTE or other mobile network.

For example, a program installed in the mobile terminal 16, such as e.g. a client, the

Short-range radio and scans for more on the

Short-range radio available mobile terminals 11-15 and 17- 21. This way, for example, an ad-hoc network 30 is formed, as shown by way of example in Fig. 1. This ad hoc network 30 represents a short-range radio network 30 self-organized among the mobile terminals 11-21. The mobile terminal 16 scans the other mobile terminals 11-15 and 17-21 via this short-range radio and receives signals indicative of the short-distance radio

Identifications from the other mobile terminals 11-15 and 17-21. The process of receiving the at least one identifying identification of at least one other mobile terminal by the mobile terminal 16 is represented by block 210 in FIG. 2a. This distinctive

Identification comprises information that uniquely identifies the respective mobile terminal, so that

Basis of the identifying identification the associated mobile terminal can be identified. These

Thus, identifying identification may thus represent, for example, a one-to-one identifier of a respective mobile terminal.

The indicative received by the mobile terminal 16

Identifications may thus be considered, for example, as a list of the other mobile terminals 11-15 and 17-21 included in the short-distance radio network 30 formed by the short-distance radio network.

Furthermore, it is assumed for the short-range radio network 30 shown by way of example in FIG. 1 that at least one of the mobile terminals 11-21 has a device for the

Position determination includes. This device for

Position determination can be, for example, a GPS receiver for determining GPS-based position data Galileo receiver for detection of Galileo-based

Position data, a GLONASS receiver for determining GLONASS-based position data or another receiver for determining position data. This position data may represent, for example, location coordinates, e.g. in Cartesian representation or in polar coordinate form, or also position data in another suitable form, e.g. Latitude and longitude straight. The position data may also include altitude information.

The mobile terminal 16 is further arranged to collect the collected identifying identifications of the other mobile terminals 11-15 and 17-20 together with the

To transmit position data of the at least one mobile terminal 11-20 to a server 40. This sending from the

at least one identifying identification and

Information comprising position data from the mobile terminal 16 to the server 40 is represented by block 220 in Fig. 2a, and in Fig. 2b the server-side receiving of this information, which is at least one of characterization

Identification of at least one other mobile terminal and position data are represented by block 250. This transmission can take place via the further radio network 50 described above. The mobile terminal 16 may also send its own identifying identification to the server 40.

Based on the received distinctive

Identifications and the position data, the server 40, the mobile terminals 11-21 in at least one group

as represented by block 260 in the exemplary method in Figure 2b, and these groups, respectively Assign position information as in the example

Process shown in Fig. 2b by block 270.

For example, assume that only one of the mobile terminals 11-21 of the short-distance network 30 can provide location data, e.g. the mobile terminal 21, the server 40 may, for example, summarize the mobile terminals 11 - 21 as a single group and this group the position data of the one mobile terminal 21 as

Assign position information. Since that is

Short-range network does not extend over long distances, but thus a better position assignment is possible, as if this group, for example, only the location information of the respective mobile radio cell would be assigned.

For example, suppose that several of the mobile ones

Terminals 11-21 of the short-distance network 30 can provide position data, e.g. the mobile terminals 16 and 21, the server 40 may determine, for example, which of the mobile terminals 11-21 are located in groups in close proximity to one another and determine these groups

Assign position information based on the multiple received position data. Thus, the present invention enables the position data provided by a mobile terminal to be used for

Positioning be used by other mobile devices 11-21. Furthermore, the mobile terminal 16 next to the

characterizing information additional position related information about mobile terminals in relation to the Short-range radio network 30 from the other mobile

Receive terminals 11-15 and 17-21 and send to the server 40. These additional positional can

For example, from the server 40 for grouping and / or to determine the group-related

Position information can be used. Furthermore, the mobile terminal can also determine its own additional position-related information with respect to the short-distance radio network 30 and also send it to the server 40.

By way of example, this additional information of one of the mobile terminals may contain a data record about the mobile terminal directly via the short-range radio network 30

connected and thus adjacent mobile terminals

include. With reference to FIG. 1 and to the mobile terminal 15, this data record could thus indicate that the mobile terminal 15 is connected directly to the mobile terminal 16, 21 and 18 via the short-range radio network 30. This additional positional information can

For example, even more information about

Short-range radio-related data of the respective mobile

Terminals include, e.g. the information as to whether the mobile terminal is a server or a master, or also the information about a measure of the reception strength of the radio signal between the respective mobile terminal and the mobile terminal directly connected directly to the mobile terminal via the short-range radio network.

For example, the server 40 may group the mobile terminals 11-21 such that in each group at least one of the mobile terminals provides its own location data, the server 40 of a group providing one based on the assigns position information determined by this group to the position data provided. If position data are provided within a group only by a mobile terminal, the server 40 can provide these

Use position data as position information for this group. For several provided

For example, position data per group, the server 40 may form an average of the various position data and assign the group this average value as position information.

After the server 40 has formed the at least one group for the short-distance radio network 30 and each of these has assigned at least one group position information, the server 40 may select, for example, targeted groups and these groups pre-determinable

Assign behavioral statements as group-related data.

For this purpose, the server 40, for example, this

Behavioral instructions in the form of group-related data are sent to a mobile terminal of the respective group, so that this mobile terminal forwards these behavioral instructions to the further mobile terminals of this group, but the server 40 can also, for example, contact each mobile terminal of a group individually. Subsequent to this sending of group-related data will be discussed in more detail with regard to the exemplary embodiments illustrated in FIGS. 5a and 5b. The server 40 may be further configured to receive information from a plurality of short-range radio networks, each indicative of identifications the mobile terminals in the respective

Short-range radio networks and position data include. Thus, the server 40 can do these different ones

Short-range radio networks each divide into at least one group of spatially adjacent mobile terminals and assign a position information to each group.

The explanations and advantages with regard to FIG. 1 and FIGS. 2 a and 2 b apply equally to the following further exemplary embodiments of the present invention.

FIG. 3 shows an exemplary grouping of a

Short-range radio network 330 between different mobile terminals 11-21 according to another exemplary

Embodiment.

This short-range radio network 330 is based on the short-range radio network 30 shown in FIG

Short-range network 330 is divided into three sub-networks 331, 332 and 333. These subnetworks 331, 332 and 333 may represent, for example, piconets of the ad hoc network short-range radio network 330, where the mobile terminal 16 acts as master for the first piconet 311, the mobile terminal 21 as master for the second

Piconetzwerk 312 and the mobile terminal 18 acts as a master for the third piconet 313.

As before with respect to that shown in FIG

Embodiment described again is assumed that the mobile terminal 16, the short-range radio network 330 according to the identifying identifications of the other mobile Terminals 11-15 and 17-21 scans and also possible position data from these other mobile

Receive terminals 11-15 and 17-21. The mobile terminal 16 further receives additional position-related information about the respective mobile terminals with respect to the short-range radio network 330, which can be used by the server 40 to divide the groups, as also optional in the first

Embodiment has been explained.

The client on the mobile terminal 16 transmits this identifying information, the location data, and the additional location-related information to the server 40.

The server 40 can now based on the additional

Information, which represent network information, make a Vorgruppierung the mobile terminals, wherein

For example, the mobile terminals 11, 12, 16 and 17 may form a first group, the mobile terminals 13, 14, 15 and 21 may form a second group, and the mobile terminals 18-20 may form a third group. For example, in mobile terminals that may be assigned to multiple subnets, such as the mobile terminal 15, the server 40 may initially be random or otherwise

Assign this mobile device to a group. The server 40 can then, for example, still more

Make changes to this pre-grouping, for example, based on the location data and / or the additional information. For example, the mobile terminal 15, which can be assigned to each of the three piconets 331, 332 and 333, also moved to another group depending, for example, on other

additional position-related information.

Based on the received position data, the server 40 of each of the three groups 331, 332, 333 can now make a

Assign position information. For this purpose, equally apply to the explanations given to the first embodiment.

If the server 40 for any of the groups none

Position data, for example, the server 40 may use the position data from neighboring groups to estimate the position of that group.

Such an exemplary variant is for the example in Figure 4a grouped short-range radio network

accepted. Assume, by way of example, that the server 40 has divided the radio network shown in Fig. 4a into the groups 410, 420, 430, 44, 450 and 460, which may have been done according to the previously described explanations.

It is further assumed that position data are not available for any of the mobile devices assigned to the group 410, whereas the server 40 has position data for the neighboring groups 420, 430, 450 and 470, for example.

The server 40 may now estimate the position of the group 410 based on, for example, the position data of the groups 410, 430, 440, and 450 adjacent to the group 410. This estimation can be done, for example, by averaging the previously determined position information of these neighboring groups 420, 430, 450 and 470. However, additional information can be used to estimate positional group 410 information. For example, position data of mobile terminals may be used to estimate the position information of group 410

neighboring groups when these mobile terminals are directly connected to a group 410 mobile terminal. For example, with reference to FIG. 4a, assuming that the mobile terminals 431 and 451, which are each directly connected to a mobile terminal of the group 410, have their own positional data, for example, this positional data may be used instead of the

Position information of the groups 430 and 450 for the

Estimation of the position information of the group 410 can be used, as by the direct connection of the mobile terminals

431 and 451 to group 410, it may be assumed that these mobile terminals 431 and 451 are spatially relatively close to group 410. In Fig. 4b is such an example of a determination

Position information 412 for the group 410 based on the position information 422 and 442 of the adjacent groups 420 and 440 and on the position data 432 and 452 of the mobile terminals 431 and 451, respectively. The averaging of the position information 422, 442 and the position data

432 and 452 may thus correspond to a cross-bearing between these position information or position data.

Fig. 5a shows an exemplary flowchart of a

Method according to another exemplary

Embodiment of the present invention for controlling a server, such as the server 40 described above. Fig. 5b shows an exemplary flowchart of a method according to another example

Embodiment of the present invention for controlling a mobile terminal.

It is assumed that the server 40 has previously determined different groups and these groups

Assigned position information, as described for example with respect to the previous embodiments.

This classification of mobile devices in different

Groups can be used to targeted

Send group-specific data to a group to execute this data on mobile devices of the selected group.

For this purpose, the server 40 first selects a group from the various groups. This selection process is represented by the block 510 in FIG. 5a. Subsequently, the server 40 sends, for example, group-specific data to one of the mobile terminals in this selected group via the further radio network, which is represented by the block 520 in FIG. 5b.

For example, with reference to the grouping shown in FIG. 3, the server 40 could select the subnetwork 333 as group 333, assuming that the mobile terminal 15 is associated with this group 333 and send the group specific data to the mobile terminal 18. At the same time, the server 40 may provide instruction data to the mobile Send terminal 18, said instruction data naming further mobile terminals 15, 19 and 20 from the selected group, to which the group-specific data to be distributed over the short-range radio network.

On the mobile terminal 18, for example, a client may be installed that is configured to receive group-specific data from the server 40 and the aforementioned ones

To receive instruction data. This reception is illustrated by block 550 in FIG. 5b. On the basis of the received group-specific data, the mobile terminal 18 can now send the group-specific data to the further mobile terminals 15, 19 and 20 named in the instruction data via the short-range radio network 30.

For example, the group-specific data

Behavioral instructions include, which then from the

respective mobile terminals of the selected group, in this example the mobile terminals 15, 18, 19 and 20, can be executed.

Alternatively, in step 410, the server 40 may also use the

Send group-specific data individually to each of the mobile devices 15, 18, 19 and 20 contained in the selected group 333 via the further wireless network, or to selected mobile terminals 15, 18, 19 and 20 of this group 333.

For example, you can target traffic jams

Instructions may be sent to mobile terminals from selected groups, for example, to form escape lanes or to maintain ideal speeds energy efficient or lead to a faster resolution of a traffic jam. At major events can

for example, public flows are better managed. In stadiums and at concerts, for example, deliberately distorted standing and arm movements can generate a variety of waves or create coordinated light animations through coordinated display animations.

All exemplary embodiments explained above can be combined with one another.
